ConcurrentSkipListSet last() method in Java

Last Updated : 21 Sep, 2018

The last() method of java.util.concurrent.ConcurrentSkipListSet is an in-built function in Java which returns the last (highest) element currently in this set. Syntax:

public E last()

Return Value: The function returns returns the last (highest) element currently in this set. Exception: The function throws the NoSuchElementException if this set is empty. Below programs illustrate the ConcurrentSkipListSet.last() method: Program 1:

Java

// Java program to demonstrate last()
// method of ConcurrentSkipListSet

import java.util.concurrent.ConcurrentSkipListSet;

class ConcurrentSkipListSetLastExample1 {
    public static void main(String[] args)
    {

        // Initializing the set
        ConcurrentSkipListSet<Integer>
            set = new ConcurrentSkipListSet<Integer>();

        // Adding elements to this set
        set.add(78);
        set.add(64);
        set.add(12);
        set.add(45);
        set.add(8);

        // Printing the highest element of the set
        System.out.println("The highest element of the set: "
                           + set.last());
    }
}

Output:

The highest element of the set: 78

Program 2: Program to show NoSuchElementException in last().

Java

// Java program to demonstrate last()
// method of ConcurrentSkipListSet

import java.util.concurrent.ConcurrentSkipListSet;

class ConcurrentSkipListSetLastExample1 {
    public static void main(String[] args)
    {

        // Initializing the set
        ConcurrentSkipListSet<Integer>
            set = new ConcurrentSkipListSet<Integer>();
        try {
            // Printing the highest element of the set
            System.out.println("The highest element of the set: "
                               + set.last());
        }
        catch (Exception e) {
            System.out.println("Exception: " + e);
        }
    }
}

Output:

Exception: java.util.NoSuchElementException
